IP expansion - scope

• Cover NGN subscribers

• 2 year storage of intercepts (currently 1 year)

• Antivirus system (is going to be delivered together with MC)

IP expansion – NGNISP requirements• 2 rack unit space in rack to mount Aggregation switch and Network Taps

• 2 free UPSed power lines (different power phases) with adequate non-earth leakage circuit breaker

• Room must have Air Conditioning. A temperature must be kept between + 10 °C and + 35 °C and a humidity between 20 % rH

to 70 % rH (non condensing).

• All of the Radius traffic must be sent via SPAN using 1GbE UTP port. The same solution like described in Filwoha location can

be used. Only Radius traffic shall be forwarded.

• From every aggregation switch the traffic (up to 2 Gbps) must be forwarded to the Monitoring Center. Every aggregation switch

in ER locations has 10GbE (fiber 1310nm LC) link which must be connected to a transport network. The transport network

must aggregate all links (from 25 locations) and send traffic to the MC - L2 transport is required (packets cannot be routed

gg g ( s) sp q (p

based on destination IP addresses). The Monitoring Center is able to get the traffic via one 10GbE (fiber 1310nm LC) link.

Network shall be ready to send traffic over additional link 10GbE (fiber 1310nm LC, blue dotted line on the picture) if overall

uplink and downlink traffic of NGN will exceed 10Gbps

• All current and future subscribers must have static IP addresses if the Radius is not in use.

• Dynamic addresses can be use only in combination with Radius authentication/authorization.

• The ISP must log all user IP address assignments and store them for at least 1 year (ISP must be able to determine who was

using specific IP address at a particular time)

• Using NTP to ensure that all devices involved in the logging of IP address assignments have properly synchronized timing. The

goal is to have all logged information with proper timestamps.

• Ethernet Frame according to IEEE 802.3 3.1.a or IEEE 802.3 3.1.b and the type (EtherType) must be 0x0800 (IPv4)

IP expansion – NGNSAN expansion – 2 years of archiving

MC voiceGIS

• Monitoring Center for the voice can be extended by Geographical

Information System (GIS)

• GIS presents location of the subscriber based on Cell_ID (less precise

than the positioning system). Accuracy of this solution depends on a size

of 2G/3G cells

event/ presenter’s name/ month, 2009 I 10© trovicor I non contractual; subject to change without notice I for internal use only

• Very cheap solution in comparison to the positioning systems

• Users must be marked before their locations can be gathered

• Integration with GSM switch vendor needed (ZTE)

• Additional Front-End for ZTE is needed as well as more space for data

and licences
